Guinness World Records title-holders are known for a wide range of skills. Be it size or strength or speed or simply good planning, you need to have something remarkable to enter the GWR universe.
Last month, six current and former record holders look to prove that, in addition to their other extraordinary talents, knowledge is chief among them.
Over the course of a week, the American TV version of Who Wants to be a Millionaire featured different Guinness World Records holders braving the "hot seat" with new host Terry Crews asking all the tough questions.
The Friday, Nov. 14 episode featured game show legend Ken Jennings, former record holder for the greatest prize money won on a TV quiz show. His iconic run on Jeopardy! in 2004 saw Ken earn $2,520,700 (£1,352,597) in winning 74 games.
Having won $58,100 on his first day, Ken made it to the $1million questionon his second day,but had to settle for a total prize haul of $100,000
Here are the other GWR personalities who all made the cut.
BOB BRETALL - LARGEST COLLECTION OF COMIC BOOKS
At last check, Bob's collection numbered 94,268 unique comic books in Mission Viejo, California, USA. He keeps his comics stored in a three-car garage and a special "comic room" within his house.
Bob's stint under the Millionaire spotlight started in confident style, but his superhero showing of general knowledge came up short after losing the $40,000 he had accumulated to end with $1,000.
ERIN LAVOIE - MOST CHRISTMAS TREES CHOPPED IN TWO MINUTES
Looking to prove her brains match her brawn, Erin aimed to add some Millionaire success to her 2008 achievement for chopping 27 Christmas trees in 120 seconds.
Erin broke her record on German television's Guinness World Records: Die GroBten Weltrekorde, so she was hoping her experience of performing under pressure on TV would stand her in good stead.
Erin didn't quite manage to reach the same highs during her time on the Millionaire hotseat - but still managed to walk away with a creditable $9,000.
MARK ANGELO - MOST SPITS AND CATCHES OF TWO TABLE TENNIS BALLS
Back in Sept. 2012, Mark "juggled" two ping-pong balls with his mouth 212 times consecutively, capping his 19 years of practice in the discipline with a record that still stands today.
Mark faired somewhat better than Erin, racking up a tidy $32,800.
STEPHEN CLARKE - PUMPKIN POWER
Stephen has broken not one, not two, but eight career world records, all with the talent of pumpkin carving.
He found his success in record categories for the most pumpkins carved in one hour (twice), fastest time to carve one tonne of pumpkins (twice), and the fastest time to carve one pumpkin (four times). The latter two are still the current world records, at 3 hr 33 min 39 sec and 16.47 sec, respectively.
Stephen answered eight questions correctly and then shrewdly withdrew after accumulating more than $42,000 in winnings.
SUSAN BARONCINI-MOE - LONGEST UNINTERRUPTED LIVE WEBCAST
Performing on Millionaire should have been a breeze for Susan, who once held her record for a nonstop performance on a show themed around business and marketing in June 2012, that lasted 36 hr 23 sec.
She was aiming to do things much quicker this time around, and looked to be on course for a strong showing having raced to the $20,000 mark in style, but sadly left with $1,000 after losing the $53,100 she had built up.
We'd like to congratulate all the Guinness World Records competitors on their performances. With their impressive displays of facts and figures knowledge they did GWR proud!
